摘要： Examples relate to a hydraulic control unit that includes a pump for increasing a hydraulic pressure of a brake fluid. The hydraulic control unit includes a discharge channel from which the brake fluid pressurized by a pump is discharged, a pulsation reducing unit disposed in the middle of the discharge channel, and a controller controlling the pump and the pulsation reducing unit. The pulsation reducing unit includes a valve housing, a fixed core fixed to the valve housing, a movable core received in the valve housing in an axially movable manner, a closing member interlocking with the movable core and closing the discharge channel, a coil disposed in a manner to surround the valve housing and the fixed core, and an inflow chamber formed by the valve housing and one end surface of the movable core, into which the brake fluid flows, and whose volume can vary.

摘要： An electropneumatic rail brake system configured to provide emergency braking including an emergency magnet valve which controls air flow into an emergency regulator valve, which valve has an emergency back-up chamber. The emergency regulator provides an output pressure nominally equal to the variable load pressure and no lower than the tare back-up. The magnet valve is closed when energized and when de-energized, pressure is allowed into the emergency back-up chamber, Regulation of the brake cylinder pressure continues during an emergency application such that the brake cylinder pressure applied during an emergency stop does not drop below a predetermined level. In the event of power-loss during an emergency brake stop, the nominal emergency brake pressure is applied to the brake cylinders.

摘要： A brake system for actuating a pair of front wheel brakes and a pair of rear wheel brakes includes a reservoir and a deceleration signal transmitter. First and second power transmission units are configured for selectively providing pressurized hydraulic fluid during a braking event. The first power transmission unit actuates a selected one of the front wheel brakes and a selected one of the rear wheel brakes. The second power transmission unit actuates the other one of the front wheel brakes and the other one of the rear wheel brakes. First and second electronic control units control the first and second power transmission units. A pair of rear brake motors selectively electrically actuate rear wheel brakes. Multiplex control of each of the pairs of front and rear wheel brakes is provided by an arrangement of first and second parallel valves for each wheel brake.

摘要： The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

摘要： An electronically controllable pneumatic braking system for a vehicle includes a first control unit for a primary system and a second control unit for a first fallback level, and a monostable fail-safety valve unit which pneumatically connects a main port, which provides a first pressure, and a failure brake port. The fail-safety valve unit is connected to both control units and in a fault situation, power failure and/or diagnostic situation of the control units, provides the failure brake pressure for triggering a failure braking operation. The failure brake port is connected to the primary system and/or to the first fallback level upstream of a functional pneumatic unit of the primary system and/or the first fallback level, in such a way that both front axle service brake actuators and rear axle service brake actuators have a brake pressure applied thereto in order to implement the failure braking operation.

摘要： The invention relates to an electromechanically actuatable pressure medium control valve (10) comprising a valve housing (12), an armature (14), a pole core (18), a valve casing (20) with a control cross-section (26.1), and a closing element (16) controlling a pressure medium flow through the control cross-section (26.1).
The invention proposes a development of a pressure medium control valve (10) of this type, which allows for a different throttling of a pressure medium flow between a first valve opening (26) and a second valve opening (28) according to the flow direction of the pressure medium flow through the pressure medium valve (10).-

摘要： A valve assembly for a vehicle brake apparatus is disclosed, including a solenoid valve, a pump housing having a bore accommodating the solenoid valve at least partially, a coil for applying a magnetic force to the solenoid valve, a circuit board configured to generate a signal for controlling opening and closing of the solenoid valve, a circuit board housing for accommodating the circuit board, a bobbin at least partially disposed inside the coil, a pin coupled to the bobbin and configured to supply an electric current to the coil, and a coil case at least partially disposed radially outwardly of the coil. Here, the bobbin is coupled with a compression unit that is in external contact with one surface of the circuit board and configured to compress the bobbin and the coil case toward the pump housing.

摘要： A valve for an air brake system on a commercial vehicle comprises a body, an inlet port connected to the body and at least one delivery port connected to the body. The inlet port has a threaded portion distal to the body and a hex portion proximate to the body. The hex portion includes a frangible feature in substantially the mid-point of the hex portion such that the valve can easily be removed from an air brake reservoir when the valve is broken at the frangible feature.

摘要： An air brake electric control valve includes a valve body, a force balance unit including a guide member, and an electromagnetic urge unit including a movable column operable to move between an urging position and a retracted position. When the movable column is at the urging position, the movable column pushes the air guide member such that a through hole of the air guide member is blocked. When the movable column is at the retracted position, a gap is formed between the movable column and the air guide member such that an intermediate section and a second passage of the valve body are in fluid communication via the through hole of the air guide member and the gap.
